This invention relates to improvements in sight for firearms.

The main objects of this invention are:

First, to provide a sight 'for firearms well adapted for rifles and thelike which has a wide range of adjustability or adaptability toconditions and the requirements of the user.

Second, to provide a firearm or gun sight assembly having a plurality ofsight elements in which the sight elements are effectively supported inerected position or in collapsed or retracted position.

Third, to provide a gun sight assembly comprising a plurality ofpeephole sight elements and post-sight elements which may be quicklyadjusted for cooperating relation.

Fourth, to provide a structure having these advantages which iseconomical to produce and may be readily applied to standard types offirearms in extensive use.

Objects relation to details and economies of the invention will appearfrom the description to follow. The invention is defined and pointed outin the claims.

A preferred embodiment of the invention is illustrated in theaccompanying drawing, in which:

Fig. 1 is a side elevation of my improved gun sight in its operativerelation to a gun barrel shown conveniently by dotted lines.

Fig. 2- is an end elevation, a gun barrel being indicated by dottedlines.

Fig. 3 is an enlarged fragmentary view in section on line 3-3 of Fig. 4,the sight elements all being positioned within the sight tube.

Fig. 4 is a transverse section on line 4-4 of Fig. 3, one of the sightelements being shown in dotted lines, the arrow indicating that it isbeing swung into the storage recess.

Fig. 5 is a fragmentary view partially in section on line 5-5 of Fig. 4.

Fig. 6 is a sectional view of the body or bracket portion, the sectioncorresponding to that of Fig. 3.

Fig. 7 is a cross section corresponding to that of Fig. 4 with one ofthe sight elements in its fully collapsed position.

Fig. 8 is a side view of four of the sight elements, two of them beingpeephole sight elements and two of them bead post sight elements.

In the accompanying drawing, l represents the barrel of a firearm suchas a rifle. The embodiment of my invention illustrated comprises abracket member designated generally by the numeral 2 having a dovetailedbase 3 adapted to be removably engaged with the dovetailed seat 4provided therefor on the firearm barrel. The bracket member comprises asight tube 5 internally threaded at each end as indicated at 6 toreceive the tubular clamping members I. These clamping members haveknurled finger piece 8 to facilitate adjustment.

The sight tube has longitudinally spaced transverse slots 9 therein eachadapted to receive a plurality of thin flat sight elements disposed insets in side by side relation.

The bracket member is provided with slot-like storage recesses l0aligned with the slots 9 and is also provided with pivot ears II and I2which are so positioned that the spaces l3 between the pivot ears arealigned with the slots 9 and the storage recesses Ill. The pivot pin I4is arranged through the pivot ears and shouldered at Ml to engage abracket pivot ear l2 and clamp the pivot ears of the bead sight elementsagainst the edges of the central pivot ear II. The nut or clampingsleeve I5 is threaded upon the pivot and has a reduced sleeve portion|5l adapted to engage a bracket pivot ear l2 and clamp the pivot ears ofthe peephole sight members against the central pivot ear II. The pivothas aknurled finger piece It while the clamping nut I5 is knurled toprovide a finger piece. The peephole sight elements I! are formed ofthin fiat stock and have pivot ears I8 receiving the pivot pin I4, thesepivot ears permitting the sight elements to be swung to retractedposition in one of the storage recesses H) or to erected position withinthe sight tube as shown in Fig. 3. The peephole sight elements havegraduated peephole openings l9 arranged with the larger to the rear asshown in Fig. 3. These peephole sight elements are arranged to be swunginto the forward slot of the sight tube.

I also provide a plurality of thin fiat bead sight elements 20 havinggraduated bead posts 2|. These sight elements 20 are annular and theirposts are radially disposed. These sight elements are provided withpivot ears 22 corresponding to the pivot ears I 8. The bead sight postsare arranged with the larger to the rear.

The inner edges of the slots 9 constitute annular shoulders 23 which areopposed to the inrbier cl'amping ends of the tubular clamping memersThis arrangement permits the sight elements to be individually andselectively adjusted and secured in their erected or retracted position,being secured in their retracted position by means or the clamping pivotand in their erected posi- IltUUHH tion by means or the tubular clampingmembers. They are very securely retained in erected position, and tofacilitate adjustment and positioning they are provided with peripherallugs 24 which constitute finger pieces and also stops, coacting stops 25being provided on the bracket member to correctly position the sightmembers in erected position.

I have illustrated and described my invention in a highly practicalembodiment. I have not attempted to illustrate or describe certainmodifications and adaptations which I contemplate as it is believed thisdisclosure will enable those skilled in the art to embody or adapt myinvention as may be desired.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. In a gun sight assembly, the combination of a bgaoket-membercomprising a sight tube having a slot transverse the axis of the tube,said bracket member having a sight element storage recess aligned withsaid slot in said tube and pivot ears having axes parallel to the axisof the tube and offset therefrom and between said tube and recess, thespace between the pivot ears being aligned with said slot and recess, apivot pin disposed through said pivot ears and provided with a clampingelement, a swingable sight'element having a pivot ear engaging saidpivot pin, whereby said sight element may be swung into said sight tubeor into said aligned storage recess, said pivot pin and clamping elementbeing relatively adjustable to clamp said sight element pivot ear, and atubular clamping member threaded into said sight tube, the inner edge ofsaid slot constituting a clamping shoulder opposed to said tubularclamping member whereby the sight element adjusted within the sight tubemay be clamped in its adjusted-position, said sight element when inclamping engagement with said clamping shoulder being disposed in theplane of the transverse slot, said tubular clamping member when loosenedpermitting the sight element to be swung onits pivot pin to theinoperative position outside said sight tube.

2. In a, gun sight assembly, the combination of a bracket membercomprising a sight tube having a slot transverse the axis of the tube,said.

bracket member having a sight element storage recess aligned with saidslot in said tube and pivot ears having axes parallel to the axis of thetube and ofiset therefrom and between said tube and recess, the spacebetween the pivot ears being aligned with said slot and recess, a pivotpin disposed through said pivot ears, and a swingable sight elementengaging said pivot pin between 5 said pivot ears and disposed in theplane of said slot whereby said sight element may be swung into anoperative position in the sight tube or into an inoperative position inthe storage recess of the bracket member.

3. In a gun sight assembly, the combination of a bracket membercomprising a, sight tube having a slot transverse the axis of the tube,sight element having an exterior rim portion to be supportingly engagedby the inside wall of the tube, said sight element being pivotallymounted to be moved through said slot laterally and upwardly from anoperative position inside said tube to outside said tube, said brackethaving means for supportingly engaging said sight element in aninoperative position outside said tube, and a tubular clamping memberthreaded into said sight tube, the inner edge of said slot constitutinga clamping shoulder opposed to said clamping member for clamping thesight element rim portion whereby the sight element positioned withinthe sight tube may be clamped in its operative position.

4. In a gun sight, the combination with a sight tube having a transverseslot through a longitudinal side thereof, one of the side walls of theslot constituting an annular clamping shoulder, a sight element,meansfor movably supporting the sight element, to permit the same to bemoved from an inoperative position outside said tube to an operativeposition in the slot of said tube, and a tubular clamping memberthreaded intosaid sight tube to coact with the clamping shoulder thereofin clamping the sight element in operative position in said tube, saidsight element when in clamping engagement with said clamping shoulderbeing disposed in the plane of the slot to permit the same to be moveddirectly to an inoperative position outside said tube. 45 ERNEST 0.SMITH.
